I was loading a 130 gr TTSX in a .30-06 with 62 gr of Big Game. Since I can't get Big Game, I needed to try something else. I noticed that Mule Deer's .30-06 loads in the Gack book showed very similar results between 62 gr of Big Game and 56.5 gr of Varget.
I tried the 56.5 gr Varget load and it shoots very similarly (group size and point of impact) to the Big Game load, but I can't do a chrono comparison since I'm out of Big Game.
